Coherence length is defined as the distance over which the laser beam can travel without experiencing a phase discontinuity. This is a critical parameter in applications such as holography and interferometry where beams may be required be split with each leg going a long distance before being recombined. The coherence length is directly related to the linewidth of the laser, and as a result, long coherence length lasers are almost exclusively single mode. Here at RPMC Lasers, we offer a wide range of diode and diode-pumped solid-state (DPS) with a coherence length of more than 50m. We offer a wide range of stabilization technologies including distributed feedback (DFB), distributed Bragg reflector (DBR), and volume Bragg grating (VBG) diode lasers as well as a wide variety of temperature and current stabilized DPSS solutions.
The search filters to the left can allow you to better sort through the full range of more than 50m coherence length lasers offered at RPMC to find the one which is best suited for your application, or you can talk to one of our laser experts today by calling 1-636-272-7227.
